The first connecting wires 308 areprovided with a plurality of cuts which disconnect the first connectingwires 308, thus ensuring that the second bonding pads on the upper layermetal mesh are insulated from both the first touch control electrodes 10and the first connecting unit 305. In FIG. 11-1, the first connectingwire is shown in bold line, the line width of the actual firstconnecting wires is the same as that of the metal wires of the meshpattern, and FIG. 11-1 illustrates the first connecting wires in boldonly for describing the first connecting wires clearly.

FIG. 11-2 is a schematic structural diagram of the metal mesh in Bridgeregion according to an exemplary embodiment of the present disclosure.As shown in FIG. 11-2, when the upper layer metal mesh and the lowerlayer metal mesh are formed the Bridge region, in which at the positionswhere there are metal wires in the lower layer metal mesh, there are thefirst connecting wires arranged in the upper layer metal mesh. And theorthographic projections of the first connecting wires in the upperlayer metal mesh on the substrate is basically overlapped with theorthographic projections of the second connecting wires on the lowerlayer metal mesh on the substrate. In the exemplary embodiment of thisdisclosure, “the orthographic projection of A on the substrate isbasically overlapped with the orthographic projection of B on thesubstrate” means that the overlap range of the orthographic projectionof A and the orthographic projection of B is greater than 90%. In anexemplary embodiment, a plurality of cuts are provided on the firstconnecting wires, and the overlap range of the orthographic projectionsof the first connecting wires of the upper layer metal mesh on thesubstrate and the orthographic projections of the second connectingwires of the lower layer metal mesh on the substrate is greater than95%. In this way, the completeness of the upper layer metal mesh in theBridge region is ensured and the reflection of metal wires in the lowerlayer metal mesh in the Bridge region is blocked by the first connectingwires disposed on the upper layer metal mesh. The reflection of metalwires in the Bridge region mainly comes from the metal wires of theupper layer metal mesh, so that the mesh pattern units in the Bridgeregion have little difference from the mesh pattern units in the Bulkregion and the Boundary region, thereby dot-shaped, line-shaped orblock-shaped mura defects in the Bridge region may be prevented.

In an exemplary embodiment, the metal mesh of the touch controlstructure layer is formed by splicing of a plurality of repeating units,which are the basic units constituting the metal mesh of the touchcontrol structure layer. The metal mesh of the touch control structurelayer may be formed by repetitive and continuous arrangement of therepeating units along a certain direction. Each repeating unit includesa plurality of mesh pattern units on which a plurality of cuts areprovided. In some possible implementations, considering the convenienceof design and flexibility of change in the design process for thedesigner, in the repeating units arrangement design performed withrepetitive arrangement mode, the repeating units arranged repetitivelymay include any one or more of basic repeating units, mirror repeatingunits, inverted repeating units and rotary repeating units, to which andthis disclosure does not provide any limit.

In an exemplary embodiment, when cuts are provided in the Bulk region,the Boundary region and the Bridge region, the cuts may include,according to the relative positions of the cuts, any one or more ofisolated cuts, continuous cuts and corner cuts, or according todirection of the cuts, the cuts may include any one or more of the firstdirection cuts, the second direction cuts and the third direction cuts,or according to the positional relationship between the cuts and thesubpixels, the cuts may include any one or more of the first cuts, thesecond cuts and the third cuts.

In an exemplary embodiment, when a plurality of cuts are continuouslyarranged in one direction, the number of cuts of the continuous cuts isless than or equal to 3 in one direction. FIG. 12-1 to FIG. 12-2 areschematic diagrams of continuous cuts in an exemplary embodiment of thisdisclosure, in which black blocks represent cuts and the cuts may beunderstood as imaginary lines for disconnecting the metal wires, anddashed lines represent the direction of imaginary lines for cutting. Inthe present disclosure, a polygonal mesh pattern unit includes at leasttwo parallel first sides and two parallel second sides, and the firstside and the second side are non-parallel. “Continuous cuts” refers tothat cuts are provided on both first sides of each of the at least onemesh pattern unit continuously arranged along the first direction. Thefirst direction intersects the first sides of each mesh pattern unit, orrefers to that cuts are provided on both second sides of each of the atleast one mesh pattern unit continuously arranged along the seconddirection. The second direction intersects the second sides of each meshpattern unit. In other words, if a polygonal subpixel includes at leasttwo parallel first side edges and both of the metal wires on the twoparallel first side edges are provided with cuts, the cuts on the metalwires on the two first side edges are continuous cuts, and the subpixelhas continuous cuts. The metal wires of the side edges of the subpixelrefer to the metal wires located in the region where the subpixelboundary is located. Subpixels refer to the light-emitting region whilethe subpixel boundaries refer to the non-light-emitting region enclosingthe subpixels. “Isolated cut” means that if only one side of a polygonalmesh pattern is provided with a cut, the mesh patter unit has anisolated cut. Or, if only one metal wire on one side edge of a subpixelis provided with a cut, the subpixel has an isolated cut. In the presentdisclosure, “parallel” refers to a state in which two straight linesform an angle larger than −10° but smaller than 10° while“perpendicular” may refer to a state in which the angle is larger than80° but smaller than 100°.

As shown in FIG. 12-1, continuous cuts and an isolated cut areillustrated with a mesh pattern. With respect to the mesh pattern unitof the first mesh row and second mesh column, if one cut is disposed onthe first side (metal wire) on the left of mesh pattern unit, anothercut is disposed on the first side (metal wire) on the right of the meshpattern unit, and the left first side and the right first side areparallel and thus, then the two cuts are continuous cuts and the numberof the cuts in the continuous cuts is 2. If another adjacent meshpattern unit in the row direction is provided with continuous cuts, thenthe number of cuts of the continuous cuts in the row direction is 3.With respect to the mesh pattern unit of the third mesh row and thesecond mesh column and the mesh pattern unit of the third mesh row andthe mesh third column, if only one side of the mesh pattern unit isprovided with a cut, then the cut is an isolated cut.

As shown in FIG. 12-1, subpixels may be used to illustrate consecutivecuts and isolated cuts. For the B subpixel corresponding to the firstmesh row and the second mesh column, if a cut is provided on the metalwire within the subpixel boundary region on the left side of the Bsubpixel, and another cut is provided on the metal wire within thesubpixel boundary region on the right side of the B subpixel, and theleft side and the right side are parallel, then the two cuts arecontinuous cuts, and the number of cuts of the continuous cuts is 2. Ifthe metal wires of the left side and right side of the G subpixeladjacent to the B subpixel in the left direction are provided with cuts,then the number of consecutive cuts in this direction is 3. With respectto the G subpixel corresponding to the second mesh row and the sixthmesh column, if a cut is provided on the metal wire within the subpixelboundary region on its upper side of the G subpixel, another cut isprovided on the metal wire within the subpixel boundary region on itslower side of the G subpixel, and the upper side and the lower side areparallel, then the two cuts are consecutive cuts, and the number of cutsof the consecutive cuts is 2. If the metal wires of the lower side andupper side of the B subpixel adjacent to the G subpixel in the downwarddirection are provided with cuts, then the number of the consecutivecuts in this direction is 3. With respect to B subpixel corresponding tothe third mesh row and the second mesh column and G subpixelcorresponding to the third mesh row and the third mesh column, if onlythe metal wire in the subpixel boundary region on the right side of Bsubpixel is provided with a cut, and only the metal wire in the subpixelboundary region on the left side of G subpixel is provided with a cut,then the cut between the B subpixel and the G subpixel is an isolatedcut.

As shown in FIG. 12-2, One set of consecutive cuts is horizontal and thenumber of cuts in the consecutive cuts is 3; the other two sets ofconsecutive cuts are diagonal and the number of cuts in each set of theconsecutive cut is 3. The diagonal direction include upper leftdirection and upper right direction, or lower right direction and lowerleft direction.

In an exemplary embodiment, for corner cuts, when there are consecutivecuts in the corner cuts in the first direction or the second direction,the number of cuts in the consecutive cuts is less than or equal to 2.FIG. 13-1 to FIG. 13-2 are schematic diagrams of corner cuts accordingto an exemplary embodiment of the present disclosure. In thisdisclosure, “corner cut” refers to that if two cuts are respectivelyprovided on a first side and a second side of a polygonal mesh patternunit, then the two cuts are a set of corner cuts, and if the meshpattern unit has corner cuts, that means turning occurred in thedirections of the cuts on both sides of the mesh pattern units.Alternatively, a polygonal subpixel at least includes a first side and asecond side which are not parallel. If the metal wires on the twonon-parallel first and second sides are both provided with cuts, thenthe two cuts are a set of corner cuts, i.e. turning occurred in thedirections of the cuts on both sides of the subpixel.

As shown in FIG. 13-1, corner cuts are illustrated with a mesh pattern.With respect to the mesh pattern unit corresponding to the first meshrow and the third mesh column, if a cut is provided on the first side onthe left of the mesh pattern unit, and another cut is provided on thesecond side on the lower-side of the mesh pattern unit, since the firstside is not parallel with the second side, then the two cuts are a setof corner cuts, and the directions of the corner cuts are left and thedown respectively. The mesh pattern unit correspond to the first meshrow and the second mesh column is adjacent to the first side, and thismesh pattern unit has consecutive cuts and thus, the corner cuts includeconsecutive cuts on the left and the number of cuts in the consecutivecuts is 2. The mesh pattern unit of the second mesh row and the thirdmesh column is adjacent to the second side, and the mesh pattern unithas consecutive cuts and thus, the lower-side of the corner cuts includeconsecutive cuts and the number of cuts in the consecutive cuts is 2.

As shown in FIG. 13-1, corner cuts are illustrated with reference tosubpixels. With respect to the G subpixel corresponding to the firstmesh row and the third mesh column, a leftward-extending cut is providedon the metal wire within the subpixel boundary region on the left sideof the G subpixel and another downward-extending cut on the metal wirein the subpixel boundary region on the lower-side of the subpixel andthus, leftward-extending cut and the downward-extending cut constitute aset of corner cuts, and the directions of the corner cuts are of leftand down. When the B subpixel whose left-side is adjacent to the Gsubpixel has consecutive cuts, the corner cuts include consecutive cutson the left, and the number of cuts in the consecutive cuts is 2. Whenthe R subpixel whose lower-side is adjacent to the G subpixel hasconsecutive cuts, then the lower-side of the corner cuts includesconsecutive cuts, and the number of cuts in the consecutive cuts is 2.

As shown in FIG. 13-2, a set of corner cuts have the directions of leftand lower right respectively includes consecutive cuts in both the twodirections and the numbers of cuts in the respective consecutive cutsare 2. Another set of corner cuts have the direction of right and lowerleft, and have consecutive cuts on the lower left, and the number ofcuts in the consecutive cuts is 2.

In an exemplary embodiment, when a plurality of sets of corner cuts areconsecutively arranged, the sets of corner cuts form an open shape. FIG.14-1 to FIG. 14-2 are schematic diagrams of open shapes according to anexemplary embodiment of the present disclosure. As shown in FIG. 14-1,the G subpixel of the first mesh row and the third mesh column isprovided with a set of corner cuts, and one end of the corner cuts isthe G subpixel of the first mesh row and the first mesh column. The Gsubpixel of the third mesh row and the third mesh column is providedwith another set of corner cuts, and one end of the corner cuts is the Gsubpixel of the third mesh row and the first mesh column. Since the endsof the two set of corner cuts do not overlapped, the shape formed by thetwo sets of corner cuts are open shape, and all the cuts in the two setof corner cuts do not form a closed loop. As shown in FIG. 14-2, the Gsubpixel of the first mesh row and the third mesh column is providedwith a set of corner cuts, and one end of the corner cuts is the Gsubpixel of the first mesh row and the first mesh column. The B subpixelof the third mesh row and the fourth mesh column is provided withanother set of corner cuts, and one end of the corner cuts is the Bsubpixel of the third mesh row and the sixth mesh column. Since the endsof the two sets of corner cuts do not overlapped, the shape formed bythe two sets of corner cuts are open shape.

According to the exemplary embodiment of the present disclosure, bysetting the relative position relationship between cuts, the cuts may beuniformly arranged on the metal mesh to the maximum extent, which mayprevent the brightness difference caused by interference among multiplecuts in one direction or one region, reduce the visibility of cuts, andmitigate the mura defect of the Bridge region.

In an exemplary embodiment, when cuts are provided in the Bulk region,the Boundary region and the Bridge region, the cuts may include,according to the directions of the cuts, at least a first direction cutand a second direction cut. Because the mesh pattern unit is a polygonformed with metal wires, thus a mesh pattern unit includes at least afirst side and a second side which are not parallel. A cut disconnectingthe first side is a first direction cut and a cut disconnecting thesecond side is a second direction cut. FIG. 15-1 to FIG. 15-2 areschematic diagrams of directions of cuts according to an exemplaryembodiment of the present disclosure. As shown in FIG. 15-1, in arectangular mesh pattern unit, the cuts disconnecting the vertical metalwires (first sides) are first direction cuts (horizontal cuts), and thecut disconnecting the horizontal metal wires (second sides) are seconddirection cuts (vertical cuts). As shown in FIG. 13-2, in a hexagonalmesh pattern unit, the cut disconnecting the upper right metal wire (afirst side) is a first direction cut (an upper left cut), and the cutdisconnecting the upper left metal wire (a second side) is a seconddirection cut (an upper right cut). In an exemplary embodiment, a firstdirection cut may be any one of a horizontal cut, a vertical cut and adiagonal cut while a second direction cut may be any one different fromthe first direction cut; a diagonal cut may be any one or more of anupper left cut and an upper right cut. In the following embodiment, itis illustrated by taking that a first direction cut is a horizontal cut,a second direction cut is a vertical cut, and a third direction cut isan diagonal cut as an example.

In an exemplary embodiment, cut density refers to the ratio of thenumber of cuts in one repeating units to the number of mesh patternunits in one repeating unit. FIG. 16 is a schematic diagram of cutdensity according to an exemplary embodiment of the present disclosure.As shown in FIG. 16, in a repeating unit there are for example 12*12rectangular mesh pattern units, and the number of mesh pattern units is144 while the number of cuts arranged in the repeating unit is 58, andthus the cut density is 58/144=0.403. Within the 58 cuts, the number ofhorizontal cuts is 31 while the number of vertical cuts is 27 and thus,the density of horizontal cuts is 31/144=0.215 and that of vertical cutsis 27/144=0.188. In an exemplary embodiment, the cut density in onerepeating units may be 10% to 90%.

FIG. 17 is a schematic diagram of one type of cuts arrangement accordingto an exemplary embodiment of the present disclosure, illustrating thecuts arrangement in a repeating unit including 12*12 rectangular meshpattern units. The 12*12 mesh pattern units in the repeating unit havethe same shape and corresponding positions as the 12*12 subpixels on thedisplay structure layer, wherein the 12*12 subpixels are periodicallyarranged in form of GBRG square. As shown in FIG. 17, the cuts in therepeating units include a first horizontal cut 901 disposed between an Rsubpixel and a G subpixel arranged horizontally, a second horizontal cut902 disposed between a B subpixel and G subpixel arranged horizontally,a first vertical cut 903 disposed between R subpixel and G subpixelarranged vertically, a second vertical cut 904 disposed between Bsubpixel and G subpixel arranged vertically.

In an exemplary embodiment, the ratio of the first horizontal cutdensity to the second horizontal cut density may be 0.7-1.3 within arepeating unit; the ration of the first vertical cut density to thesecond vertical cut density may be 0.7-1.3 within a repeating unit. Insome possible implementations, the first horizontal cut density may beequal to the second horizontal cut density; the first vertical cutdensity may be equal to the second vertical cut density. The firsthorizontal cut density is the ratio of the number of first horizontalcuts 901 and the number of mesh pattern units in the repeating unit, andthe second horizontal cut density is the ratio of the number of secondhorizontal cuts 902 to the number of mesh pattern units in the repeatingunit. The first vertical cut density is the ratio of the number of firstvertical cuts 903 and the number of mesh pattern units in the repeatingunit, and the second vertical cut density is the ratio of the number ofsecond vertical cuts 904 to the number of mesh pattern units in therepeating unit.

For example, within the region of 12*12 mesh pattern units as shown inFIG. 17, the numbers of second horizontal cuts 902 are 2, 4, 2, 2, 3,and 3 in the first, third, fifth, seventh, ninth and eleventh mesh rowsrespectively, and the number of second horizontal cuts 902 in therepeating unit is 16; the numbers of first horizontal cuts 901 are 3, 1,2, 4, 2 and 3 in the second, fourth, sixth, eighth, tenth and twelfthmesh rows respectively, and the number of first horizontal cuts 901 inthe repeating unit is 17; and thus the ratio of the first horizontal cutdensity to the second horizontal cut density is 1.06. For anotherexample, in a repeating unit of 12*12 mesh pattern units illustrated inFIG. 17, the numbers of first vertical cuts 903 are 3, 2, 2, 2, 3 and 2in the first, third, fifth, seventh, ninth and eleventh columnsrespectively, and the number of first vertical cuts 903 in the repeatingunit is 14; the numbers of second vertical cuts 904 are 2, 3, 2, 3, 3and 3 in the second, fourth, sixth, eighth, tenth and twelfth columnrespectively, and the number of second vertical cuts 904 in therepeating unit is 16; and thus, the ratio of the first vertical cutdensity to the second vertical cut density is 1.14.

Since the first horizontal cuts are arranged between R subpixels and Gsubpixels, it may be understood as that one first horizontal cutcorresponds to one R subpixel and one G subpixel and thus, when thenumber of first horizontal cuts is 16, 16 first horizontal cutscorrespond to R subpixels and G subpixels. Since the second horizontalcuts are arranged between B subpixels and G subpixels, it may beunderstood as that one second horizontal cut corresponds to one Bsubpixel and one G subpixel and thus, when the number of secondhorizontal cuts is 17, 17 second horizontal cuts correspond to Bsubpixels and G subpixels. In this way, regarding all the horizontalcuts, a number of those cuts corresponding to R subpixels is 16 and anumber of those cuts corresponding to B subpixels is 17; and a number ofthose cuts corresponding to G subpixels is 33. Thus the numberscorresponding to R subpixels and B subpixels are close, and the numbercorresponding to G subpixel is equal to the sum of the numberscorresponding to R subpixels B subpixels.

Since the first horizontal cuts are arranged between R subpixels and Gsubpixels, it can be understood that one R subpixel has one adjacentfirst horizontal cut and one G subpixel has one adjacent firsthorizontal cut. Therefore, when the number of first horizontal cuts is16, 16 R subpixels have adjacent first horizontal cuts and 16 Gsubpixels have adjacent first horizontal cuts. Since the secondhorizontal cuts are arranged between B subpixels and G subpixels, it canbe understood that one B subpixel has one adjacent second horizontal cutand one G subpixel has one adjacent second horizontal cut. Therefore,when the number of second horizontal cuts is 17, 17 B subpixels haveadjacent second horizontal cuts and 17 G subpixels have adjacent secondhorizontal cuts. In this way, of all the subpixels, there are 16 Rsubpixels adjacent to horizontal cuts, 17 B subpixels adjacent tohorizontal cuts and 33 G subpixels adjacent to horizontal cuts; thenumbers of R subpixels adjacent to horizontal cuts and B subpixelsadjacent to horizontal cuts are close; the number of G subpixelsadjacent to horizontal cuts are the sum of the numbers R subpixelsadjacent to horizontal cuts and B subpixels adjacent to horizontal cuts.

The cuts in a repeating unit may be divided into first cuts and secondcuts. First cuts are cuts provided between an R subpixel and a Gsubpixel, i.e., include first horizontal cuts and first vertical cuts.Second cuts are cuts provided between a B subpixel and a G subpixel,i.e., include second horizontal cuts and second vertical cuts. In anexemplary embodiment, the ratio of the first cut density to the secondcut density may be 0.7-1.3 within a repeating unit.

In an exemplary embodiment, when subpixels are periodically arranged inother ways, the cuts in the repeating unit may be divided into firstcuts, second cuts and third cuts, wherein the first cuts are arrangedbetween R subpixels and G subpixels, the second cuts are arrangedbetween B subpixels and G subpixels, and the third cuts are arrangedbetween R subpixels and B subpixels. In a repeating unit, the ratio ofthe first cut density to the second cut density may be 0.7-1.3; theratio of the second cut density to the third cut density may 0.7-1.3;the ratio of the first cut density to the third cut density may be0.7-1.3. In some possible implementations, the first, second and thirdcuts may all include any one or more of horizontal (first direction)cuts, vertical (second direction) cuts and diagonal (third direction)cuts and the diagonal cuts may include any one or more of upper leftcuts and upper right cuts, to which the present disclosure does notprovide any limit.

According to the exemplary embodiment of the present disclosure, thefirst cut density, the second cut density and the third cut density inthe repeating unit are set to be equal to or close to each other, suchthat the numbers of different color subpixels corresponding to the cutsare basically the same, the numbers of different color subpixelsadjacent to cuts are basically the same, and the cuts are evenlydistributed among the different color subpixels, which may reduce thevisibility of the cuts and mitigate the mura defect in the Boundaryregion.

In an exemplary embodiment, the Bulk region, Boundary region and Bridgeregion are all provided with a plurality of cuts. The cuts in the Bulkregion form dummy regions and electrode regions respectively. The cutsin the Boundary region achieve the isolation of the first touch controlelectrodes and the second touch control electrodes. The cuts in theBridge region form connecting structures. Because there are contiguouszones among the Bulk region, Boundary region and Bridge region, the muradefect of Bridge region may be mitigated by proper setting of cutdensity of the contiguous zones.

As shown in FIG. 3, the repeating units constituting the metal mesh ofthe touch control structure layer may be divided into the firstrepeating units C1 including the cuts in the Bridge region; the secondrepeating units C2 including the cut in the Bulk region; and the thirdrepeating units C3 including the cuts in the Boundary region.

FIG. 18 is a schematic diagram of region arrangement according to anexemplary embodiment of the present disclosure. As shown in FIG. 18,compared with the first region defined as the region where the Bridgeregion is located, multiple second regions may be defined in the regionwhere the Bulk region is located, such as second regions A1-A5 locatedin the direction of right of the first region, second regions B1-B5located in the direction of lower right of the first region, and secondregions C1-C5 located in the direction below the first region. Takingthe second region in the direction of right as an example, the secondregions A1-A5 may be defined as separate regions or may be defined asoverlapping regions. The ratio of cut density of the first region to thecut density of any second region refers to the ratio of cut density ofthe first region to the cut density of the second region A1, or, theratio of cut density of the first region to the cut density of thesecond region A2, or the ratio of cut density of the first region to thecut density of the second region A3, the ratio of cut density of thefirst region to the cut density of the second region A4, or the ratio ofcut density of the first region to the cut density of the second regionA5.

According to the exemplary embodiment of the present disclosure, withthe setting of the relationship of cut densities among Bridge region,Bulk region and Boundary region, the cuts difference among Bridgeregion, Bulk region and Boundary region is reduced and thereby thebrightness difference among Bridge region, Bulk region and Boundaryregion is reduced, the visibility of cut may be reduced, and the muradefect of Bridge region can be mitigated.

In an exemplary embodiment, the plurality of cuts in the first, secondand third repeating units each may include first cuts, second cuts andthird cuts according to the positional relation between cuts andsubpixels, wherein the first cuts are arranged between R subpixels and Gsubpixels, the second cuts are arranged between B subpixels and Gsubpixels, and the third cuts are arranged between R subpixels and Bsubpixels.

In an exemplary embodiment,the repeating unit is the repeating unit of the Bulk region, i.e., thesecond repeating unit. As shown in FIG. 23, the repeating unit has afirst characteristic length Si in the horizontal direction and a secondcharacteristic length S2 in the vertical direction. In an exemplaryembodiment, the first characteristic length Si is greater than or equalto the second characteristic length S2, the first characteristic lengthSi is referred to as the maximum characteristic length S of therepeating unit, i.e., the maximum characteristic length S is the maximumvalue of the first characteristic length Si and the secondcharacteristic length S2.

FIG. 24 is a schematic diagram of the spatial frequency of the viewer'seyes in a range of 1 degree. Generally, a reciprocal of adistinguishable visual angle (degree) is used as a unit of the spatialresolution ability of eyes (i.e., visual acuity). The minimumdiscernible visual threshold of normal eyes is about 0.5, and themaximum visual range is 200 degrees (width)×135 degrees (height). Thespatial frequency of the viewer's eyes within 1 degree range isexpressed as Cycle per Degree (CPD for short), referring to the numberof cycles of black and white stripes scanned in each roll of the eyeballwith 1 degree. As shown in FIG. 24, the spatial frequency of theviewer's eyes within 1 degree range (CPD) is related to the distance (L)from the viewer's eyes to the display screen and the cycle of thestripes (h), and the calculation formula is:

CPD=1/(57.3*arctan(h/L))

For a given stripe cycle (h), the greater the distance (L) is, thegreater the CPD is. For a given distance L, the smaller the h is, thelarger the CPD is. The research shows that with respect to the touchcontrol structure layer formed by repeated splicing with multiplerepeating units, the multiple repeating units will form light and shadestripes, and the cycle of the light and shade stripes (h) is the maximumcharacteristic length S of the repeating units, so the spatial frequencyof the viewer's eyes within 1 degree range (CPD) meets thatCPD=1/(57.3*arctan (s/l)), and furthermore:

S=L*tan(1/(57.3*CPD))

In an exemplary embodiment, the distance (L) from the viewer's eye tothe display screen is 100 mm to 1000 mm, CPD≥10, the maximumcharacteristic length of the repeating units is the maximum size of therepeating units in a certain direction, and 1/(57.3*CPD) is a radianvalue.

When a viewer watches a touch control structure layer, the distance Lfrom the viewer's eyes to the display screen may be divided into twotypes: short viewing distance for a small scale screen and long viewingdistance for a large scale screen. In an exemplary embodiment, regardinga short viewing distance, the distance L from the viewer's eyes to thedisplay screen may be 100 mm to 400 mm, and regarding a long viewingdistance, the distance L from the viewer's eyes to the display screenmay be 400 mm to 1000 mm.

In an exemplary embodiment, for a short viewing distance, the maximumcharacteristic length S of the repeating units is arranged to be 0.2 mmto 0.4 mm, so that the spatial frequency of the viewer's eyes within 1degree range (CPD) is greater than or equal to 10. In some possibleimplementations, the maximum characteristic length S of the repeatingunits is arranged to be 0.25 mm to 0.35 mm.

In an exemplary embodiment, for a long viewing distance, the maximumcharacteristic length S of the repeating units is arranged to be 0.4 mmto 1.2 mm, so that the spatial frequency of the viewer's eyes within 1degree range (CPD) is greater than or equal to 10. In some possibleimplementations, the maximum characteristic length S of the repeatingunits is arranged to be 0.5 mm to 1.0 mm.

In some possible implementations, the maximum characteristic length S ofthe repeating units may be arranged to enable the spatial frequency ofthe viewer's eyes within 1 degree range (CPD) to be greater than orequal to 30.

In the exemplary embodiment of this disclosure,through arranging the maximum characteristic length of the repeatingunits, the spatial frequency of the viewer's eyes within 1 degree rangeis increased, the sensitivity of the viewer to distinguish the light andshade stripes is reduced, thus preventing the mura under differentazimuth and reducing the visibility of the mura.
